Do I need a permit for shed or accessory structure in Phoenix?
It depends. Whether shed or accessory structure needs a permit in Phoenix comes down to the details of your project.
Small accessory structures under a size threshold are often exempt from a building permit, but the threshold and setback rules differ by jurisdiction because Arizona has no statewide code; Phoenix, Maricopa County, Tucson, and Pima County each set their own limits. A permit exemption does not waive zoning setbacks, HOA rules, or an electrical permit if the shed will be wired. Phoenix exempts detached accessory structures of 200 square feet or smaller from a building permit; anything larger than 200 sq ft requires a permit. Running electrical or plumbing to any shed requires its own permit regardless of the structure size, and Zoning Ordinance setback and lot-coverage rules still apply to exempt sheds. A shed that will have electricity, plumbing, or a permanent foundation falls outside the usual small accessory building exemption, which generally covers simple unpowered structures only. Electrical and plumbing work each normally require their own permit and inspection even when the structure itself would have been exempt, and many jurisdictions require a licensed electrician or plumber to pull them. Zoning setbacks, height limits, and lot coverage are reviewed separately from the building permit, so confirm placement with your local department before the shed is delivered or poured.
